The provision of warning signs is a matter for local authorities. Such signs are either prescribed in regulations made under section 95 of the Road Traffic Act, 1961, or authorised for use under the same section. A specific warning sign relating to cattle or other farm animals crossing a road has not been prescribed or authorised. However, Wexford County Council are at present conducting an experiment on behalf of my Department using a prototype sign warning motorists of cattle crossing at locations on national road N25 in the county.
